Images in jar files

Posted on 2000-05-16

How can I tell the java interpreter where to look for image files in a Jar file?

For example, I have a class called "MyClass.class" and an image file called "MyImage.jpg".      The constructor of MyClass will create an instance of ImageIcon("MyImage.jpg").     Now I want to package MyClass.class into a Jar file and I also want to include "MyImage.jpg" in that jar file as well.

However, the java interpreter seems to expect MyImage.jpg from the directory where the main Class is stored.    Even though "MyImage.jpg is in the same archive as "MyClass.class", MyClass won't be able to find MyImage.jpg unless there is another MyImage.jpg in the directory where the main Class resides.

How can I tell the java intepreter to look for "MyImage.jpg" in the archive that MyClass.class comes from?    Is there any work-around or something?

Thanks alot.

Hi mtngu76...
URL url = MyClass.getClass().getResource("<dir>/MyImage.jpg");

ImageIcon = new ImageIcon(url);

best regards...

Hi jerch,

Thanks for the comment.    I actually tried your suggestion and it did work, except that I think MyClass.getClass() should be MyClass.class instead.

I think that the applet will know to look in the jar file automatically-you dont have to tell it anything because if you include  codebase tag pointing to your jar file it will look in it first then it will look in the directory where the class file is ran from....here is an example

<applet code=Nickel.class codebase="your.jar" width=75 height=30>
<param name=text VALUE="Discriminate">
<param name=sound Value="nickel_disc.au">

Thanks okcman,  I will try your suggestion later, but I'm afraid I can't take it as an answer because I might need to have more than one jar file, each jar file may need to have its own images.

jerch, thank you.
